OIL-BURNER ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 24, 1914.

Application filed September 5, 1913. Serial No. 788,292.

To all whom it may concern:

Be. it known that I, IVILLIAM Moms, a citizen of the United States, residing at Ilidley Park, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Oilllurner Attachments, of which the following is a specification.

In oil fired furnaces the burners are usually held in fixed relation to the opening through which the spray is delivered Where worked in combination with a supplementary hot or cold blast the spray is usually blown through the blast, is thereby deflected from its intended course and partly thrown against blast pipe surfaces or delivery-hole surfaces where the atomized oil collects again in drops, thus not only lowering the efficiency of the burner, but also causing premature ignition of spray and development of heat where it is not wanted. \Vhere high pressure burners are used a considerable noise is oftentimes experienced if the spray is not completely inclosed or if the burner is not in air tight connection with the furnace. A rigidly connected, non-removable burner is always subjected to the radiating heat from the furnace inlet and is not readily accessible for cleaning or inspecting or adjusting the atomizing parts, which usually will carbonize and especially so when the burner is not removed from the furnace after the shut downs.

It is the object of my invention to overcome these ditiiculties by providing a burner attachment combined with a suitable refractory spray inlet, to make the direction of spray subject to adjustments in all directions within certain limits; to provide means for making the burner readily accessible for inspection of the atomizing parts without detaching it from the line; to provide means for attaching the burner air tight to the furnace so as to avoid or greatly subdue the noise inherent to the operation of high pressure burners; to provide means whereby the condition of spray or flame can be observed; to provide means whereby the escape of blast can be prevented while the burner is not in operation and to provide means whereby the blast can be regulated at the attachment The means aforementioned are illustrated in the accompanying drawings which show the three forms of my invention and it will he noted that in each drawing the same figures denote the same part.

Figure I denotes a section through the lllll'lltl' attachment along the line GD of Fig. III and viewed as indicated by the arrows. Fig. II denotes a section through the burner attachment along the line .\B of Fig. I and viewed as indicated by the arrows, the burner, however, being removed. Fig. III is an end view of burner attachment as viewed from A of Fig. I, the burner, however, being removed. Fig. IV denotes an end view of refractory inlet block as viewed from B of Fig. I. Fig. V denotes a section through burner attachment of another form of my invention along the line (I) on Fig. VIII and viewed as indicated by the arrows. Fig. VI denotes a section along the line AB of Fig. V and viewed as indicated by the arrows. Fig. VII denotes a section along theline of EF of Fig. V and viewed as indicated by the arrows. Fig. VIII denotes an end view of burner attachment as viewed from A of Fig. V. the burner, however. being removed.

In Figs. I, II, III and IV--5 shows a burner the discharge end of which is screwed into the hollow ball zone 6, the inner part of which fits into the socket 7, said socket being also hollow and having a flaring opening 8 opposite the ball seat. The socket has two outside threads, one near the flaring opening and one near the ball seat and between the threads is a groove or offset 10 which forms a seat against the face of door 11, when socket 7 is screwed into opening of door 1].. The ball zone 6 with burner 5 is adjustably connected to socket 7 by nut 9, having a spherical bore. The burner 5 being connected to the stationary air or steam and oil supply pipes by suitable means, such as flexible hose, has by the means aforedescribed a universal adjustment of limited range. Door 11 has a conical projection 12 on its inner face in axial alinement with opening into which socket" and swings around bolt 36. The arrangement al oredcscribed enables the burner to be swung out from its working position for adjustment, cleaning and for protection from radiating heat after shut-downs, thereby obviating the carbonization at the atomizing parts.

Blast attachment 14 has a peephole 18 over the door opening, which hole is covered ordinarily by a cover 19, swinging on bolt 21 and being fitted with a glass plate 20 of suitable color to observe conditions of flame etc., in the furnace. The peephole also serves as ignition hole. Blast attachment 14 is in connection with a blast gate 24- having a stem 25 with a handle 29, and being inclosed between the flange 22 of blast attachment and flange 23 of blast connection 26, said flanges being bolted together by bolts 28. The blast connection 26 receives blast pipe 27. The blast attachment 14 has on its face opposite the burner a flange 17 whereby it is butted against the refractory inlet piece said inlet piece is walled in the furnace lining 34 and has a hole which is principally conical; the shape of the outside opening 31 of said hole corresponding with the shape of the opening of blast attachment, taking in the cut-out 33 for peephole. The inside opening 32 of said hole, being larger than 31, takes also in a part of cutout 33.

In Figs. V, VI, VII and VIII5 shows a burner, the discharge end of which is screwed into the hollow ball zone 6, the inner part of which fits into the socket 7, said socket being also hollow and having a flaring opening 8 opposite the ball seat. The socket has two outside threads, one near the flaring opening and one near the ball seat and between the threads is a groove or offset 10 which forms a seat against the face of door 11 when socket7 is screwed into opening of door 11. The ball zone 6 with burner 5 is adjustably connected to socket 7 by nut 9, having a spherical bore. The burner 5, being connected to the stationary air or steam and oil supply pipes by suitable means such as flexible hose, has by the means aforedescribed a universal adjustment of limited range. Door 11 has a conical projection 12 on its inner face in axial alinement with opening into which socket 7 is screwed. Said projection fits a conical seat in blast attachment 14 to which door 11 is connected by hinges 13 on door and lug 15 on blast attachment. 16 denotes the hinge pin. The door 11 can be locked by latch which fits a projection 37 on door and swings around bolt 36. The arrangement aforedescribed enables the burner to be swung out from its working position for adjustment, cleaning and for protection from radiating heat after shut-downs, thereby obviating the carbonization at the atomizaliases ing parts. Blast attachment 14 has a peephole 18 under the door opening, which hole is covered ordinarily by a cover 19 swinging on bolt 21* and being fitted with a glass late 20 of suitable color to observe conditions of flame etc. in the furnace. The peephole also serves as ignition hole. Blast attachment 14 has a conical bore 38, flaring toward the furnace and merging into a cylindrical enlargement 41. The conical bore aforementioned is intersected by a cylindrical bore of lower part 39 of blast attachment into which fits blast pipe 27*. In the conical bore of blast attachment 14: is movably fitted hollow cook which has an opening 46 for the introduction of blast from pipe 27. Opening 46 ends at an angle-shaped circular flange of cook 40, which flange is pressed against the face of cylindrical enlargement 41, by a helical spring 19. handle 48 located near the inlet end of cock, and the stem of said handle can move in a slot 4.? of blast attachment 14:. The attachment as aforedescribed is fastened to a plate 42 by means of bolts 43; said plate having an opening 31 corresponding with opening 31 of refractory inlet piece 30. Inlet piece 30 is walled into the furnace lining 3& and has a flaring hole with openings 31 and 32 and a cut-out 33. The regulation of blast is efiected by turning cock 40 with handle 48.
